Dr. Higgins will teach you and help you teach yourself any language. It works like a quiz, asking you the translations of words and
keeping score of your correctness. It includes a number of quizzes for
self-study in different languages (English, Spanish, Finnish, and a bit
of Japanese). It's very easy to add your own lists, thanks to a simple file
format.

Forxx is a language for text processing, inspired by Forth and REXX. It is a stack-based, extensible language which provides both an interactive environment and the ability to compile and run programs.

JLearnIt is a thematic dictionary that allows you to learn vocabulary with a questionnaire. You can also translate text (word by word), search for incomplete words, sort the languages in alphabetical order, rearrange the order of the languages, save your score, save as HTML, and show only the languages you're interested in. Each word is rated according to frequency of use. You can choose to see only the words of a certain range of frequencies or to be asked for words of that level. You can also add and delete your vocabulary and categories, and cut/copy/paste between a spreadsheet program and JLearnIt. You can change the language and the skin of JLearnIt. You can get more information about the word on the Internet and save your configuration. JLearnIt won't ask you the same word if you know the word. It won't ask you for the word that starts with the same letters as the translation. You can edit words and set properties for this word.

LayerD is an effort to develop an extensible framework for programming languages. It features unlimited compile time programmability, modular design, pluggable code generation, unified high level semantics, multiple source languages, integration of RAD tools with compilers and languages, development of domain specific languages, development of abstract software, extensive features for code generation and meta-programming. Its implementation is able to implement software for .NET and Java bytecode using one high level language that is extensible by programming compile time functionality. There is a Java front-end that allows programming for this new framework using a well known language.

PHP-to-Scala Migration Helper is a tool that enables individuals and organizations with a significant PHP codebase to migrate to a Java-centric environment completely free of any PHP source code, PHP tools, PHP servers, and PHP developers. PHP-to-Scala Migration Helper is technically a PHP compiler, but it translates to readable, maintainable source code rather than machine code. Its goal is not to make PHP code run faster, but it is not an unwelcome side effect.

Voca is a vocabulary trainer for foreign languages. It allows you to create and manage your own word lists and share them online. You can make word lists for any language or for other things you want to memorize. It lets you do different types of exercises, including grammar, pronunciation, and picture tests.

Vocabularium creates Spanish-English podcasts to help with vocabulary learning. A vocabulary topic and the subtopics which you want to include in the podcast can be selected. The program outputs a WAV file (or MP3 if Lame is installed) that reads a list of Spanish words and phrases with English translations based on that topic. Several vocabulary topics are built into the program. Under Windows, Vocabularium is designed to work with any SAPI 5 voice. Under Linux and Mac OS, it currently works with Cepstral voices, including the free demonstration versions.
